The Port of Seattle confirmed that the August 24 system outages at Seattle-Tacoma International Airport were due to a ransomware attack by the criminal group Rhysida. The attack disrupted various airport operations, including internet, phones, email, and baggage services. Despite demands, the Port refused to pay the ransom and is investigating what data was stolen, including potential employee and passenger information. Rhysida may retaliate by posting stolen data on the dark web. The Port has taken steps to enhance its IT security and continue restoring systems. There has been no new unauthorized activity since the attack, and the Port remains committed to notifying affected stakeholders.
